Abstract

A powerjack includes a base, a lift member, a lift mechanism supporting the lift member on the base, and an electric motor operably connected to lift mechanism, for operating the jack. The jack may be combined with a power cord having two ends, with one end operably connectable to the motor and having a power source attachment on the other end. Optionally, there may be at least one accessory light operably connected to the power cord. A light accessory that may be used apart from the jack includes a power cord, an inlet plug, a source plug, and an accessory light connected to the power cord.
